Foam Blaster AC Coil Cleaner Foam Spray | HVAC Coil Cleaner for AC Unit | Professional Deep-Penetrating Formula for Evaporator (No Rinse) & Condenser (Light Rinse) - 3 Pack

Work great 👍🏼

Good stuff to clean out condenser fins on AC units

I've been using this product on my Mom's indoor HVAC unit that has been badly neglected for many years. There is literally a compacted dirt cake around the coils underneath the fins. Standard foam spray does little to help, but makes the exterior "look" clean. This spray is more heavy duty and precise. With delayed foaming action, it allows the foam to reach the deeply embedded dirt. Still, on a system that hasn't been cleaned in a severely long time, even the best products struggle. I've used all three cans, and every time more dirt flakes work themselves out of the fins. The problem is that any remaining dirt migrates over time, gets stuck again in a different area, and causes dripping of water that falls onto the filter itself. I'm planning on buying another set of this brand. My best advice for a badly fouled indoor coil is to spray from both sides of the fins, top side and bottom side, use a soft paint brush the gently brush out the dirt flakes, use a properly sized fin comb to reach into hard to reach corner spots and smooth out any damaged fins, follow with a light rinse using a spray bottle, distilled water is preferable but not absolutely necessary. If I do buy another set of cans, I will update my review and let everyone know the results. This product is so far the best one I've used, is easy to use, and probably highly effective for an average dirty HVAC coil. For a compacted dirt cake like mine, be prepared to be persistent, multiple cleanings will be necessary to break all that dirt free.

As advertised. Good product. Got the smell out of the car AC condenser.

I got this trio as a few years back I did not know the grid in an AC needs regular cleaning and I had to ditch an insanely good powerhorse AC cause of that ignorance. Since then EVERY YEAR I spray my whynter 14,000 BTUs with these sprays. I also do the split unit. So glad I found this spray. My Whynter has been going strong for the last 7 years. Cleaning my ACs has become a right of passage every year. It pays off in extreme heat alters when my place is a frgid 18C while outside there is a humidex og 45C. Cannot praise this product enough! I wish they would come in spray bottles instead. Not for some environmental reason but to get every ml of it intead of a useless at the end aerosol spray cans. Product deserves a 85% score. Still room for improvement!
